If I’m dead, I absolutely would have no quarrels with people eating my body. Nothing to complain about since I hold no beliefs that when I die, my body needs to be intact for me to go to a heaven like place.

Also, who cares what any family members would think. It’s my body, not theirs. If I don’t mind people nibbling on my corpse, then I’d hope any family that cares about me is able to respect that wish.
